Application filed March 8, N12. Serial No. 682,426.

To aZZ whom it may concern:

Be it known that I, WILLIAM H. Wins- LOW, a citizen. of the United States, residing at (hicago, in the county of Cook and State of Illinois, have invented a. certain new and Improved Burner. of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention consists of a burner construction for brazing or l'using metals adapted to project against the work a liame which is tubular inform.

In connection with the brazing or fusing of tubes in place, it is common to use a burner from which the flame is projected in a single jet and to move this jet along the work as the proper temperature is reached. The difiiculty with this, particularly in fusing tubes in a sheet of metal, as is necessary in connection with boiler construction, is that the point of beginning the work is chilled and set by the time the fusing flame is moved around the end of the tube and reaches the starting point to finish the oper ation. As a result, it frequently happens that the joint made at this point is imperfect. Furthermore, considerable time is required to successfully heat the different portions of the end of the tube. By my present invention the entire end of the tube is heated at the same time and fused to the head thus avoiding the dilficulties referred to.

My improved burner construction is also characterized by suitable means carried by the burner for alining the same so that the discharge orifice is in proper position to heat the work to be done.

The several drawings illustrating my invention are as follows:

Figure 1 is a plan view of a portion of the end of a boiler showing the tubes in place which tubes are to be secured to the head by fusion. Fig. 2 is a sectional view of the parts shown in Fig. 1 taken along the line 22 and in this figure the burner is shown in broper position for fusing the end of one of the tubes. Fig. 3 is a view similar to Fig. 2, showing a modified form of alining means employed in connection with the burner. Fig. 4c is a sectional view of the burner shown in Fig. 2 taken along the line -ll. Fig. 5 shows in a View similar to log. 2 a modified form of burner construction. Fig. 6 is a sectional View taken along the line 66 in Fig. 5.

Similar numerals refer to similar parts throughout the several views.

As shown in the drawings, the burner consists essentially of a shell 1 adapted to receive the gas to be burned and with the shell there is associated a core 2 so disposed as to leave a narrow annular opening 3 at the end of the burner from which the gas is projected, thus forming a tubular flame. T he annula aperture 3 is constructed preferably of a diameter corresponding with the diameter of the portion of the work to be heated or fused. In the particular connection illustrated in the drawings, aperture 3 is of practically the same diameter as the outside of the tubes 4 which are to be fused into the head 5 of the boiler structure. Grooves (3 are formed in the outer face of the head 5 to cause the portion of the head surrounding the end of the flue and the end of the tube, to be heated at practically the same rate in order that they may together reach the fusing point.

The shell 1 of the burner has secured thereto an arm 7 from which the rods 8 extend in a direction parallel with the axis of the burner and terminate in plugs 9 adapted to enter tubes 4: adjacent to the one being heated. Since the tubes 4 are disposed in regular order in the head 5, this forms a convenient means for alining the burner with the work to be done.

In the modified form of construction shown in Fig. 3, the core 2 has secured to it a rod 10 connected with the plug 11 adapted to enter the tube 4 upon which Work is being done. This construction affords a means for alining the burner with the work to bei done if the tubes 4 are irregularly disose p In the modified form of burner construction shown in Figs. 5 and 6 the shell 12 is provided with a solid end 12* through which a plurality of small holes 13 is drilled in annular arrangement. Each of the holes 13 thus made serves to direct an individual jet of gas from the burner and the jets combine outside of the burner to constitute in efi'ect a tubular flame thus securing all of tubular flame produced may either be of circular cross-section, as shown in the drawings, or of 'other a-nd irregular cross-section if desired.

\Vhile I have shown my invention in the particular embodiment herein described, I do not, however, limit myself to this construction, but desire to claim any equivalent that may suggest itself to those skilled in the art.

What I claim is:

1. In combination, a manually movable burnerfor brazing or fusing metals having a nozzle delivering a hollow cylindrical flame, and a gage attached to said burner, said gage having-a conical member fitting into regularly spaced openings in said work to bring the flame of said burner into accurate alinement aboutan opening in said work.

2. Means for joining tubes to a boiler tube sheet, or the like, by autogenous welding, comprising a burner delivering a hol low cylindrical flame of a diameter corresponding to the adjacent edges of the tube and sheet to'be joined, gage-means secured to said burner and having a cylindrical plug fitting closely within an open tube but burner delivering a hollow cylindrical flame of an outline corresponding to the edge of the tube and the adjacent part or parts to which it is to be joined, gage-means comprising a cylindrical plug with a tapered end adapted to enter the open end of one of said tubes to aline the burner with the edges to be joined, said gage-means being adjustable with respect to the parts to be joined to allow of proper adjustment of the flame relatively to the tubes to be joined.

4. Means for joining tubes to a tube-sheet or the like by autogenous welding, said means comprising a burner delivering a hollow cylindrical flame of a diameter corresponding to the adjacent edges of the tube and sheet to be joined, gage means secured to said burner, said gage means comprising a plug with a tapered front portion of a. diameter less than the open end of the tube, and a rear portion of a diameter substantially that of the open tube, said plug beingrelatively movable axially of the tube to permit adjustment of the burner flame relatively to the work.

In witness whereof, I hereunto subscribe my name this 29th day of February, A. D. 1912.

WILLIAM H. WINSLOW.
